System, method and computer readable medium for determining users of an internet service

- PERFTECH, INC.

An internet service provider (ISP) is configured to analyze data sent by a user to determine a subscriber account associated with the data and a user associated with the data. A database is then queried to determine the number of users of the subscriber account, with a number above a threshold indicating a likely theft of service. This automatic process is accompanied by automated messaging to the user with information as to the measures taken and remedial options. The messaging may be different dependent on whether the user is deemed to be an authorized user having subscriber account administration rights.

FIELD OF THE INVENTION

This disclosure relates to managing subscribers of an internet service provider (ISP) and in particular to determining the number of separate user browsing workstations utilizing a single subscriber's internet service. The disclosure has particular application for preventing theft of service from either the ISP and/or the subscriber but it is not intended that the disclosure be limited thereto.

BACKGROUND OF THE INVENTION

Most broadband Internet Service Providers, ISPs, supply access to their Internet access network through the use of a Cable modem, DSL modem, or Wireless modem. The majority of subscribers to these services typically utilize a router incorporating Network Address Translation (NAT) as a firewall and also as a means to permit multiple personal computers (PC)s in the residence to utilize simultaneous access to the Internet.

Many of the routers are wireless routers permitting residential PCs to access the Internet through either a wired or wireless (Wi-Fi) connection to the router.

The ISP can utilize existing network devices that can observe the activity occurring at the subscriber modem at the Internet Protocol (IP) level. However, according to Internet Protocol and the design of NAT routers, the activity observed at the modem appears to originate at a single IP device, the NAT router, and evidence of the number of real workstations that are active behind the NAT router, and even cascaded NAT routers, is hidden.

ISPs typically have Terms of Service and agreements in the contracts with the subscriber that prohibits the subscriber from extending the Internet access beyond the boundaries of the residential premises. However, inexpensive, off-the-shelf NAT routers can be interconnected and cascaded by simple wired and wireless connections in an arbitrary tree-and-branch topology that provides full, unhindered Internet access to all participants. This simple extensibility, the very high speeds now offered by ISPs, and the easily-hidden installation of the interconnections make it difficult to detect where service re-distribution is occurring. In addition, the widely used Wi-Fi wireless routers are frequently installed with the default configuration that provides free, unhindered access to all within the umbrella of the signal, often extending throughout an entire multi-tenant building or buildings. Problems with this situation include theft-of-service resulting in lost revenue to the ISP as well as dissatisfied subscribers whose performance is being compromised by unknown parasitic users causing support problems.

What is required, is a system, method and computer readable medium that is capable of determining the presence of multiple users on a single subscriber account.

 DETAILED DESCRIPTION OF THE INVENTION

In the Applicant's earlier patent applications, U.S. Ser. No. 10/023,674 and U.S. Ser. No. 10/623,893, the entire contents of which are explicitly incorporated herein by reference, the present Applicants described networks in which communications could be provided from an ISP to a subscriber of the ISP. In the referenced applications, a redirection device was placed in the path of upstream traffic from the subscriber. The redirection device, operating under the control of a consolidating and management device elsewhere in the network, processed upstream data packets to determine when targeted communications to the subscriber were required.

The present embodiments utilize many of the features and functionalities of the networks described in the Applicant's earlier patent applications referenced above. In FIG. 1, there is shown a system or network 10 in accordance with an embodiment of the disclosure. In the network 10, an ISP 12 provides a link between a subscriber device 14 and the internet 16. For the sake of clarity, in the following embodiments the subscriber device 14 will be referred to specifically as a personal computer, or PC. However, it will be readily understood by the person skilled in the art that the subscriber device 14 may be any internet enabled device such as a personal computer (PC), laptop, palm device, mobile telephone, gaming console and the like, and all such internet enabled devices are to be considered equivalent.

The network 10 includes at least one redirection device 21 that is placed at the path of upstream traffic 15 from the subscriber 14, either in the path or in a position to monitor the path. As described in the above referenced earlier applications, the redirection device 21 may be placed at many points within the network 10 and is preferably placed at an edge of the network that represents the last scaleable point in the operator's network. In one embodiment, the redirection device 21 is placed within the ISP 12. The term redirection device is used herein in order to provide consistency with the Applicant's earlier patent applications referenced above. The person skilled in the art will understand from the foregoing description that in the context of the present disclosure, the redirection device may not perform a redirection function in all embodiments.

The network 10 also includes a consolidating and management device 26, for example of the type as described in the Applicant's earlier applications referenced above. The consolidating and management device 26 is operatively associated with the redirection device 21 to form a data processing system, and more particularly a packet processing system, as will be described in greater detail below.

The ISP 12 includes a router or switch 22, a redirection device 21 as described above and an address provisioning database 23. The address provisioning database 23 stores associations between subscriber accounts of the ISP and IP addresses allocated to the subscribers. A second database 24 stores associations between subscriber accounts of the ISP and users of the subscriber accounts, as will be described below. The consolidating and management device 26 provides a query engine for accessing data from the databases 23, 24 in response to requests from the redirection device 21.

While two databases 23, 24 are illustrated and described herein for clarity, the person skilled in the art will readily understand that the two databases 23, 24 can be consolidated into a single database or that the two databases can be divided into a higher number of databases. For example, the databases 23, 24 may be consolidated with a database for storing an association between a subscriber and an electronic mail sending profile of the subscriber, as described in the Applicant's application Ser. No. 12/004,634, now issued U.S. Pat. No. 8,700,715, the entire contents of which are herein incorporated by reference. Alternatively or in addition, the databases 23, 24 may be consolidated with a database for storing an association between a subscriber and a shared secret as described in the Applicant's application Ser. No. 12/004,645, now issued U.S. Pat. No. 8,161,284, the entire contents of which are herein incorporated by reference.

Downstream traffic from the internet 16, indicated by path 28 is routed by the router 22 to the intended subscriber 14. Upstream traffic in the form of data packets 27 follow the path 15 from the subscriber 14 to be routed by the router 22 to the redirection device 21, thence back to the router 22 and onto the internet 16. In an alternative embodiment shown in FIG. 7, upstream traffic 15 passes directly through the Internet provider with the addition of a “mirror port” or “tap” allowing the redirector, 21, to monitor the upstream traffic.

The operation of the system 10 will now be described with reference to FIG. 1 and to the flowchart 100 illustrated in FIG. 2. At step 101, data is received from the subscriber 14 and a subscriber account associated with the data message is identified at step 102. The system then determines a user associated with the data message (step 103) and associates the user with the subscriber account (step 104).

In one embodiment, the method steps described above are performed within the ISP as illustrated in the flowchart 200 of FIG. 3. At step 201, data packets 27, such as URL page requests, originating at the subscriber are received in the ISP 12 and provided to the router 22. The router 22 passes selected packets to the redirection device 21 for processing. In one embodiment, the router passes packets derived from implanted cookies as will be described below.

The redirection device 21 first analyzes the data packet 27 to retrieve an IP address of the data packet 27. The redirection device 21 forwards the IP address to the consolidation and management device 26, which executes a first query on the address provisioning database 23 to retrieve a subscriber account identity associated with the IP address. The redirection device 21 then retrieves a user identity from the data packet 27 and logs an association between the user identity and the subscriber account in the database 24.

At the time of logging the user association, or at some other time, the consolidation and management device 26 executes a second query on the subscriber/user association database 24 to perform a count of the number of users associated with the subscriber account to determine if additional action is required (step 202). If the count is within allowable limits, then no additional action is required at the time of logging the user association, and the data packet is re-routed back to the router 22 where it continues to be processed by the ISP as usual. However, if the user count is outside allowable limits, then the ISP may take appropriate action, such as redirecting the URL page request (step 203).

The ISP 12 may be configured to take different actions based on the count of users. In one embodiment, a threshold number of users may be set, either by the ISP or by an authorized user of the subscriber account using a web based form when initializing the subscriber account. When a new user attempts to communicate with the ISP, the redirection device may determine that the addition of the new user to the subscriber account will exceed the allowed user threshold and thus the ISP may re-direct the new user to notification pages indicating an excess count of users. Other methods for automatically blocking network communications to the new user may be apparent to the person skilled in the art and are considered equivalent. Blocking access to an illegitimate user will prevent the user from illegally accessing the network, as desired. However, if the new user is a legitimate user, that user will takes steps to remedy the situation with the ISP, which may uncover other, illegitimate, users of the subscriber account.

In one embodiment, the consolidation and management device 26 may periodically execute a count query on the user association database 24. Whenever a count of users associated with a subscriber account exceeds an allowed threshold, a notification may be sent to an authorized user of the subscriber account indicating the count status and suggesting remedies to fix the problem. A message may be sent through any suitable medium such as by an e-mail to an e-mail address registered with the subscriber account.

In an alternative embodiment, a web-browser message may be sent to a user of a subscriber account using the techniques described in the Applicant's earlier applications referenced above. For example, with reference to FIG. 4, when a user association count exceeds an allowed threshold, a flag may be set in a policy database 38 that identifies the subscriber account as requiring notification of the count. When the redirection device 21 receives a web page request, the redirection device 21 processes the request to determine the IP address. The redirection device 21 then checks, via the consolidating and management device 26 whether a notification is pending for the current subscriber account associated with the IP address. If a notification is pending, the redirection device 21 provides to the subscriber an HTML redirection to destination server 39 that combines the destination URL in the page request and the URL for the message into a new page redirection for the subscriber's browser to fetch. In one embodiment, in addition to the requested page content 42, the new page 40 includes a banner 41 or similarly visible message that indicates to the user 14 that the subscriber account has an excess number of users. The banner message 41 may indicate a possible cause, such as an unencrypted wireless link, as well as a hyperlink 44 to a downloadable facility for remedying the problem. The downloadable facility and/or the banner message 41 may include a reset facility for resetting the user count on the subscriber account once the problem has been acknowledged and verified by an authorized user of the subscriber account. In one embodiment, the new page 40 may include an authentication code that verifies the authenticity of the count notification to the subscriber. In one embodiment, the authentication code may be a shared secret, for example as described in the Applicant's application Ser. No. 12/004,645, now issued U.S. Pat. No. 8,161,284, referenced above.

In one embodiment, the user identity is retrieved by first placing a hidden browser cookie incorporating a unique, logged, identifying number, possibly generated randomly and possibly other information such as time and date, with the user through the issuance of an associated bulletin message with no visibility to the user. Techniques for placing the cookie are described in the Applicant's earlier patent applications referenced above. Upon later browser activity, the cookie is retrieved to identify each separate browser. Data derived from the retrieved cookie can be used to uniquely identify the user as separate from other users detected at the account. The cookie may be placed and retrieved at varying intervals to optimize the accuracy of the count of users associated with a subscriber account or to observe the flux of continuously different transient users as may occur in an insecure Wi-Fi network accessible from a public area.

In one embodiment, the user identity may be derived from internet browser requests by observing and determining a user “fingerprint” of each browser on an account through the discrimination between host headers propagated by the users' browsers to any accessed internet site. This header includes identification of the users' operating system and version, browser and version, and the suite of plug-ins available within that browser configuration. The user fingerprint may be associated with the subscriber identity and stored in the database 24 or may be hashed in order to allow enumerating of separate users but to assure user privacy in the logs.

In one embodiment, the redirection device processes the data packets to determine a Media Access Control (MAC) address of the network-facing IP device on the account, most frequently a NAT router. The MAC addresses are assigned to manufacturers and most frequently can identify the likely vendor of a wireless router used on the account. Associating MAC addresses of the routers and other devices that interface with the ISP with the subscriber accounts can aid in identifying where theft of service is occurring, as these devices are typically fixed for a particular subscriber account.

The consolidation and management device 26 may periodically execute a query on the database that determines the most recent activity of the users associated with the subscriber account. If an associated user has not had any activity within a predetermined timeframe, for example one month, then the consolidating and management device 26 updates the database 24 by removing the inactive user, thereby reducing the count of users associated with the subscriber account. In one embodiment, the inactive user is only removed from the count, for example by resetting an ACTIVE status flag, rather than deleting the user from the subscriber account, so that any user fingerprint is maintained on the database and can be reestablished if that user again becomes active. The indication of a continual flux of new users with others becoming inactive can indicate an instance of a publically-available Wi-Fi associated with the account even though the absolute count at any point in time may not be very high.

The user association database may indicate one or more users of a subscriber account as authorized users. For example, a default authorized user fingerprint may be derived from a user that first registers the subscriber account with the ISP. The registering user is the most likely authentic user. Other authorized users may be nominated, for example through a web based form. An authorized user may be a user with subscriber account administration rights and is therefore authorized to undertake remedial actions. In one embodiment, the display of the notification may require the provision of a shared secret, for example as described in the Applicant's application Ser. No. 12/004,645, now issued U.S. Pat. No. 8,161,284, referenced above. The requirement for a shared secret ensures that warning notifications are only provided to authorized users of the subscriber account.

In one embodiment depicted in FIG. 5, the ISP 12 includes at least one processor 51 operatively associated with at least one memory 52. The memory 52 stores an instruction set 500 executable on the processor 51. Executing the instructions causes the processor 51 to receive data from a subscriber account (501). The processor 51 then determines a number of users associated with the subscriber account (502) and compares the number of users with a threshold (503). The processor 51 then determines an action to be taken depending upon an outcome of the comparison (504). In one embodiment, the action taken may be any of the actions described previously.

In FIG. 6, there is illustrated a network 70 in which a premises 60 includes four workstations 61, 62, 63, 64 connected to the ISP 12 via a wireless router 65. Of the four workstations, workstation 61 is considered to relate to an authorized user of the subscriber account. An additional workstation 66 is outside of the premises 60 but within the network coverage provided by the router 65. In an example of the systems described above, an allowed threshold of four users may be associated with the subscriber account. When the fifth user at unauthorized workstation 66 connects to the ISP 12 through the wireless router 65, redirection device 21 associates the fifth user with the subscriber account in the database 24 and determines that the allowed threshold is exceeded. The user's requested web pages may include a notification that the allowed user count has been exceeded or a request to contact the Internet Provider may be preferable to protect the privacy of the account holder. Other users 62, 63, 64 will also received similar notifications and redirections when URL page requests are made. The notifications and redirections will continue, either with every page request or periodically, until action to remedy the high user count is taken and the count is reset. In addition, when workstation 61 connects to the ISP, web page requests are interpreted by the user association database 24 as originating from the authorized user of the subscriber account and thus the web page requests are redirected to incorporate a link to downloadable remedial and count reset facility.

The presently described embodiments demonstrate mechanisms that automate the identification of likely accounts where intended or unintended theft of service is occurring and provides remedial actions through automated communications to the identified subscriber workstations. The communication can continue to encourage the subscriber to “lock down” their wireless network with authentication passwords and encryption by means of simple instructions or even a “click-to-fix” link to a downloadable automated facility that will do it for them. The communications can also dissuade intentional theft of service by providing a display of a message that demonstrates that the ISP is aware of the large number of users on the account.

An advantage of the embodiments herein described include that subscriber account violations can be rapidly detected using network devices that are relatively simple to install within the ISP and do not require all network traffic to pass through them. In particular, the redirection device 21 requires only read-only access to the data packets that it processes both for enumerating the number of users as well as communicating back to the users that there is a problem. A further advantage is that the embodiments may be implemented without updates being required to subscriber hardware or software and thus are instantly applicable across all subscribers to the ISP.

While one redirection device is shown within the ISP, the person skilled in the art will readily understand that any number of redirections devices may be provided for processing upstream data packets. In particular, separate redirection devices may be provided for separate channels within the ISP. Typically, a single consolidating and management device can be used to manage a plurality of redirections devices and to execute the queries to the databases. However, the person skilled in the art will readily understand that a plurality of consolidating and management devices may be employed.

While a single ISP has been described and illustrated, the person skilled in the art will readily understand that a plurality of ISPs may be provided that utilize a common data processing system or that each have an associated data processing system as described above.

Although embodiments of the present invention have been illustrated in the accompanied drawings and described in the foregoing description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications, and substitutions without departing from the spirit of the invention as set forth and defined by the following claims. For example, the capabilities of the invention can be performed fully and/or partially by one or more of the blocks, modules, processors or memories. Also, these capabilities may be performed in the current manner or in a distributed manner and on, or via, any device able to provide and/or receive information. Further, although depicted in a particular manner, various modules or blocks may be repositioned without departing from the scope of the current invention. Still further, although depicted in a particular manner, a greater or lesser number of modules and connections can be utilized with the present invention in order to accomplish the present invention, to provide additional known features to the present invention, and/or to make the present invention more efficient. Also, the information sent between various modules can be sent between the modules via at least one of a data network, the Internet, an Internet Protocol network, a wireless source, and a wired source and via plurality of protocols.
